Sven has recently developed a new type of solar cell. When he tests how efficient it is at converting light energy into electrical energy, he finds that it is 54% efficient. Sven publishes these findings in a scientific journal. Martha decides to repeat Sven's experiment, but she finds that the new solar cell is only 38% efficient at converting light energy into electrical energy. What should Martha do with her new findings?
